How to connect your phone to a Xiaomi TV via WiFi: A complete guide

Modern multimedia systems allow you to transform simple content viewing into a full-fledged home entertainment experience, and wireless connectivity is a key element here. Owners Xiaomi People often wonder how to maximize the potential of their TV by mirroring their smartphone. It's truly convenient: photo albums, videos from the gallery, or even a mobile game screen can be displayed on a large screen in seconds.

The main tool for achieving this task is technology Mi Smart, which is built into the Android TV operating system used in most of the brand's models. The synchronization process doesn't require expensive cables or additional adapters, as everything you need is already available. The main thing is to understand which data transfer protocols your model supports and how to properly activate the desired mode.

In this article, we'll cover all available connection methods in detail, from standard system functions to specialized apps. You'll learn how to troubleshoot common connection errors and why your phone sometimes simply doesn't detect your TV, even though both devices are on the same network. Follow the instructions to enjoy content on the big screen without lag or interference.

Preparing equipment and checking the network

Before you start setting up Mi Remote or built-in streaming features, you must ensure that your network equipment is functioning correctly. A fundamental condition for a successful connection is that both devices are on the same local network. This means that both the smartphone and TV must be connected to the same router, whether via a wired connection or Wi-Fi.

A common mistake users make is ignoring the frequency range. If your router is broadcasting two networks— 2.4 GHz And 5 GHz, make sure both devices are connected to one of them. Although modern routers can combine ranges under a single name, sometimes manually separating them can help resolve device visibility issues on the network.

⚠️ Note: If you are using a guest Wi-Fi network or a provider network with web page authentication, devices may not be able to see each other due to router security restrictions.

It's also worth checking that the wireless module is enabled on your TV. On some models, Wi-Fi may be disabled by software during initial startup or after a factory reset. To check, go to the settings menu and ensure the connection is active and the signal is stable.

• 📡 Make sure both devices are connected to the same Wi-Fi network.
• 🔄 Check if AP Isolation mode is enabled on your router.
• 📶 Assess your signal strength: 4K video transmission requires high speed.
• 🔋 Charge your smartphone, as screen mirroring drains battery quickly.

Connection stability directly impacts image quality. If you plan to stream large files or play games, it's recommended to use the 5 GHz band, which provides higher throughput.

Using the built-in Cast feature on Android

The easiest and fastest way to display an image is to use the native "Cast" function, which is built into the Android operating system. This method is based on the protocol Google Cast or Miracast, supported by the platform Android TVYou won't need to install any additional software if both devices run on the Google ecosystem.

To begin the process, pull down the notification shade on your smartphone and look for the "Cast," "Smart View" (on Samsung), or "Projection" icon. Once the search is activated, the system will scan for available devices on the network. Your TV should appear in the list. Xiaomi with the corresponding model name.

If the device is found, tap it. A connection confirmation prompt may appear on the TV screen, which you'll need to confirm with the remote. After this, the image from your mobile phone will be copied completely to the big screen. Image quality will depend on the smartphone's processor speed and Wi-Fi speed.

⚠️ Please note: When using the Screen Mirroring feature, your smartphone may become hot and the battery may drain faster than usual due to the high load on the GPU.

It's important to note the difference between casting a browser tab or app and full screen mirroring. Some apps, such as YouTube or Netflix, have their own Cast button within the interface, allowing you to use your phone as a remote control without hogging its processor with the video stream.

• 📱 Open the Quick Settings panel on your smartphone.
• 📺 Select the "Cast" or "Connect to device" option.
• 🔗 Wait until your TV's name appears in the list of available ones.
• ✅ Confirm the connection on the TV screen if required.

In some cases, the system may prompt you to enter the code displayed on the TV for confirmation. This is a standard security procedure to prevent unauthorized access to your display.

Mi Home app and Xiaomi ecosystem

For smartphone owners deeply integrated into the ecosystem Xiaomi, the best solution would be to use the official app Mi HomeThis software suite not only allows you to control your smart home but also effectively interact with your TV. The app's interface is optimized for easy searching and connecting to the brand's devices.

After installing and logging into the app, you need to add your TV to the list of devices, if this hasn't already been done automatically. The system usually automatically detects new devices on the local network. Once you add your TV to Mi Home, you gain expanded access to its features, including file management and media server functionality.

One useful feature is the ability to transfer photos and videos from your phone's gallery directly to the TV via the app interface. This eliminates the need to search for files through the TV's built-in media player. Furthermore, Mi Home allows you to use your smartphone as a touchpad remote, which is especially convenient for text input.

Using official software guarantees the best compatibility, as the communication protocols are optimized by the manufacturer's engineers. However, please note that some features may require selecting the "China" region in the app settings, which can sometimes be confusing for new users.

The app also features "Mi Drop" (or a similar feature depending on the MIUI version), which allows you to transfer files over Wi-Fi Direct at high speeds, bypassing quality compression. This is a great way to quickly transfer large videos for later viewing.

Why might the Mi Home app not see the TV?

Often, the problem lies in the region settings. If your account is registered in the "Russia" or "Europe" region, and your TV has a Chinese firmware version (or vice versa), they may not be able to communicate with each other. Try changing the region in the Mi Home app settings to "China" or the one that matches the region of the Mi account linked to the TV. Also, make sure the app has all the permissions to access your local network and location.

Miracast technology and wireless display

Protocol Miracast Miracast is an industry standard for wireless video transmission, independent of any specific brand. Unlike Chromecast, which requires internet access for some features, Miracast creates a direct Wi-Fi connection between your phone and TV. This makes it ideal for use even without internet access.

On TVs Xiaomi This feature is often called "Wireless Display" or "Screen Mirroring." To activate the signal, launch the appropriate app on your TV or find it in the Input menu. Once launched, a connection message will appear on the screen.

On the smartphone side, especially if it's not a stock Android, the function may have different names: "Projection," "Cast," or "Smart View." The operating principle is the same: the device searches for available Miracast receivers and establishes a connection. The advantage of this method is minimal latency, which is important for showing presentations or simple games.

⚠️ Please note: When connecting via Miracast, the phone's screen resolution may be stretched to cover the entire TV, which will result in image distortion if the aspect ratios do not match.

The advantage of this technology is that it doesn't require installing apps on the TV. It's built into the Wi-Fi module's hardware. However, if the TV's Wi-Fi drivers are unstable, the connection may frequently drop or become choppy.

• 📡 Miracast works directly, without using a router (Wi-Fi Direct).
• 🎮 Latency is lower than when using software methods.
• 📺 Supports audio and video transmission.
• 🔒 The connection is protected by WPA2 encryption.

It's worth remembering that when actively using Miracast, the phone cannot simultaneously distribute the Internet through its access point, since the Wi-Fi module is busy transmitting the video stream.

Third-party streaming apps

If the standard tools don't provide the required functionality or don't work correctly, third-party solutions can help. Google Play and the TV app store offers a variety of utilities that expand the capabilities Mi SmartSome of the most popular are Web Video Caster And TvCast.

These apps can often pull video streams from browsers that don't natively support TV streaming. You simply open a website with a video in the app's browser, and it redirects the link to the TV, which plays the content natively. This reduces the load on your smartphone.

Another class of programs are keyboard and touchpad emulators. If your original remote is lost or its buttons are stuck, apps like "TV Remote Control" allow you to fully control the Android TV interface from your smartphone screen. They use standard ADB or HTTP protocols to transmit commands.

When choosing third-party software, pay attention to the presence of ads. Free versions are often overloaded with banners that can obscure controls. Paid versions usually avoid this drawback and offer a more stable connection.

Using third-party DLNA servers allows you to share your phone's file system with your TV. You can set up automatic indexing of new photos taken on your phone so they immediately appear in your gallery on the big screen.

Troubleshooting and diagnostics

Despite the simplicity of the technology, users often face a situation where the TV Xiaomi isn't visible in the list of available devices. The first step should always be to reboot the router. Network equipment tends to accumulate errors in the ARP table, which prevents devices from finding each other.

The second important aspect is firewall and antivirus software. If your smartphone has an aggressive antivirus installed or "Private Network" mode is enabled in the Wi-Fi settings, it may block ports needed for device detection. You should set the network status to "Trusted."

It's also worth checking the date and time on both devices. Clock desynchronization can lead to security certificate errors, preventing the handshake between the devices. Set automatic time synchronization via the network.

⚠️ Note: Interfaces and menu item names may differ depending on the version of the Android TV operating system and the regional firmware of your Xiaomi TV.

If all else fails, try resetting your TV's network settings. This will delete all saved Wi-Fi passwords, but it often resolves issues with a frozen network module. After resetting, re-enter your network password.

• 🔁 Restart your router, phone, and TV.
• 🛡️ Check your firewall settings and network type (Private/Public).
• 🕒 Sync date and time across all your devices.
• 📶 Make sure that access point isolation is not enabled on your router.

In rare cases, the problem may be due to outdated TV firmware. Check for system updates.
